Freelancing in Belgium

Belgium has a large and growing freelance sector — over 1 million self-employed professionals (zelfstandigen/indépendants). Whether you're a consultant, developer, designer, or any independent professional, freelancing in Belgium requires proper registration, tax compliance, and social security enrollment. For non-EU freelancers, a professional card is also needed. For company formation, see our accounting services and company registration guides.

Sole Proprietorship vs BV/SRL

Belgian freelancers have two main options:

Rule of thumb: if your net freelance income exceeds approximately €40,000/year, a BV/SRL is almost always more tax-efficient due to the 20% SME corporate tax rate on the first €100,000 (vs up to 50% personal tax). See our BV vs NV comparison for more on company types.

How to Register as a Freelancer

EU Citizens — 5 Steps

1. Register at the commune — within 3 months of arrival (get E card)
2. Join a social insurance fund — Acerta, Securex, Liantis, Partena, Xerius, etc. (within 90 days of starting)
3. Register at enterprise counter — get your CBE enterprise number via an ondernemingsloket/guichet d'entreprises
4. Activate VAT — Belgian VAT number (BE + enterprise number)
5. Join a health insurance fund — mutuelle/ziekenfonds (CM, Solidaris, Partena, etc.)

Non-EU Citizens — Additional Step

Before the above steps, non-EU freelancers must obtain a professional card (beroepskaart/carte professionnelle). This requires a business plan, proof of qualifications, and approval from the regional authority. Processing: 1–4 months. Then apply for a D visa at the Belgian embassy.

Taxes for Freelancers

Social Security

All Belgian freelancers must pay quarterly social security contributions:

Social security covers: pension, healthcare (via mutuelle), disability, family allowances, and the bridging right (droit passerelle/overbruggingsrecht) in case of bankruptcy or forced cessation.

VAT for Freelancers

• Registration: Mandatory for all freelancers (see VAT registration)
• Exemption: Available if turnover <€25,000/year (no VAT charged, no input deduction)
• Standard rate: 21% on most services
• Filing: Quarterly via Intervat (see VAT guide)
• B2B EU services: Reverse charge applies — no Belgian VAT charged to EU business clients

Practical Tips

• Separate bank account — keep personal and business finances separate from day one
• Track all expenses — deductible expenses directly reduce your tax base
• Set aside 40–50% of revenue for taxes and social security
• Advance tax payments — make quarterly voorafbetalingen to avoid surcharges
• Get an accountant — even a basic bookkeeper saves money through proper deductions
• Consider BV/SRL early — if income is growing, converting sooner saves more tax
• Supplementary pension (VAPZ/PLCI) — tax-deductible pension savings for self-employed (up to ~€3,900/year)
